Song in the JC Penney commercial?

It's the new one, with a man and a woman walking around in a snowy town. The singer is a woman, I don't remember any of the lyrics though, sorry.

Any help would be greatly appreciated.

the song is Music Box by Regina Spektor. You can listen to the entire songand view the lyrics here:
